FILTRATION-FAUCET.

To all whom it may concern:

Be it known that I, BELA BERGER, a citiyen of the United States, residing at Los iingelcs, in the county of Los Angeles and State of California, have invented new and useful Improvements in Filtration-Faucets, of which the following is a specification.

This invention relates to filtration faucets; and it has for its object to provide improvements in faucets of the character stated which. will be superior in point of positiveness in operation, convenience and facility in control and operation, and adaptability to varying conditions of use. and which will be generally superior in point of serviceability.

The invention consists in the rn'ovision, construction, combination association and relative arrangement of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claim.

In the drawing :Figure 1 is a top plan view of a filtration faucet constructed and organized according to the invention; Fig. 2 is avertical sectional view of the same, taken upon the line 22, Fig. 1, and looking in the direction of the appended arrows; and Fig. 3 is a vertical transverse sectional view of the same, taken upon the line 33, Fig. 2, and looking in the direction of the appended arrows; parts being omitted and broken away for clearness of illustration.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring to the drawing, the letter A designates a tubular body which is threaded at one end, as at a, for connection with a service pipe, and is provided at the opposite end with a discharge nozzle or spout m. At an intermediate point in its length the tubular body A is shown as provided with a filtration cup B which comprises a member Z) integral with the body A and a detachable member beneath the same, a packing (Z being interposed between the said mem bers. Clamping means, 6 and f, are provided for holding together the members and c, and each of the said clamping means may comprise a bolt 4 pivotally connected at 5 with the member 6 and provided at its free end with a wing nut 6 adapted to engage a member 7 upon the lower member '0. The bottom of the member 0 may be provided with a central orifice 9 from which depends a spout 10 through which the filtered Specification of Letters Patent.

liquid is discharged, a filtering block 11 being arranged within the member 0 over the discharge spout and the upper surface of the filtering block being covered by a layer 12 of asbestos. This filter may be of any suitable construction, since it constitutes no part of the present invention, the said invention residing in the valve for controlling the supply of water to the filter and the discharge of water through the spout m.

Located directly above the filtration casing B is a valve casing 13, the lower end of the valve casing communicating with the interior of the tubular body portion A through the opening 11, while opposite sides of the valve casing communicate through a plurality of lateral ports 15 with the top of the filtration casing. A somewhat similar valve casing 16 is provided at the pointof communication of the tubular body A with the delivery spout m, and valves 9 and h respectively are slidably mounted within the valve casings 13 and 16 so as to control the end and side openings thereof.

E designates the valve mechanism for the valve g, and F designates the valve mechanism for the valve h. The valve mechanism E comprises a valve stem 17 the inner end of which has a threaded connection, as at 18 with and within a nipple 19 which is threaded into the valve casing 13 so that the inner end thereof is spaced from and parallel to the back of the valve 9. A stufling box 20 is shown as provided at the upper end of the nipple 19, and the upper end of the valve stem 17 is provided with a handle or hand grasp 21 while the inner end of the valve stem is formed with a socket 23 loosely receiving a valve spindle 22 projecting aXially from the back of the valve 9. A coil spring 24 surrounds the valve spindle 22 and is interposed between the inner end of the stem 17 and the valve so as to normally tend to force the valve downwardly and cause the valve to close the opening 14. The

"valve mechanism F is substantially the same in construction and comprises a valve stem 25 the inner end of which has a threaded connection, as at 26, with and within a nipple 27 which is threaded into the outer end of the valve casing 16 so that the inner end thereof is spaced from and parallel to the back of the valve h. A stuffing box 28 is provided at the outer end of the nipple 27 and the outer end of the valve stem 25 is provided with a handle 29, while the inner end of the said valve stem is formed with. a socket 331 loosely receiving a valve spindle projecting axially from the back of the valve h. A coil spring 32 surrounds the spindle" 30 and is interposed between the inner end of the stem 25 and the valve it so as to normally tend to force the valve away from the inner end of the valve stem.

The two valve mechanisms E and F are substantially alike and constitute the present invention, no claim being made to the filter mechanism which is merely shown incidentally and may be of any suitable construction.

"faucets constituting the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawing and the following statement: With the parts in the positions shown in the drawing, liquid entering the tubular body A is free to traverse the port 14 into the valve chamber 13, and thence to fiow through the ports 15 into the filtration casing or shell B, passing through the asbestos sheet 12 and the porous block 11 successively, and thence through the orifice 9 and the spout 10. This course of the liquid through the faucet is permitted by the elevation of the valve stem 17 which permits the fluid to press against the under side of the valve 9 and raise it against the opposition of the tension means or spring 24. The communication of the tubular body A with the delivery spout m is prevented by the seating of the valve 72, in its casing 16, the valve stem 25 being adjusted in its nipple so. as

, to hold the valve in its seated position under high tension of the spring 32. Thus, any fluid entering the tubular body A is prevented from exit therefrom save after the filtering action of the asbestos sheet'12 and the porous block 11. If, now, the valve stem 17 be manipulated to positively seat the valve 9 and close the ports 15 and the port 14, no liquid can pass through the faucet.

- will unseat the valve 72, and find its way into the delivery spout m. It is manifest that both valves 9 and it may be simultaneously closed or seated, or simultaneously unseated, or that either of the same may be unseatcd while the other is seated, in accordance with predetermination as to use of the filtration casing B and the delivery spout m, either separately or simultaneously, or in accordancewith the non-use of both of the same, as may be desired. Thus, the faucet may deliver both filtered and unfiltered liquid at the same time, or either filtered or unfiltered liquid, or neither of the same.

The provision of the tension means or springs 24: and 32, disposed respectively between the valve 9 and its stem and the valve h and its stem, enables a more delicate adjustment of faucet conditions, as the yield of each spring may be utilized against the pressure of the liquid in the faucet, to entirely overcome said pressure and prevent flow, or to permit flow under fine gradations of regulation.

Having thus described my invention I claim and desire to secure by Letters Patent:

The herein described valve including a valve casing formed at an end and a side thereof with inlet and discharge openings respectively, a valve slidably mounted within the valve casing and adapted to control the said openings, a spindle projecting axially from the back of the valve, a nipple removably applied to one end of the valve casing and projecting into the said valve casing where the end thereof is spaced from and parallel to the back of the valve, a valve stem extending through the nipple and threaded therein, the outer end of the valve stem being formed with a handle, while the inner end of the valve stem is formed with a socket loosely receiving the spindle of the valve which slides freely therein to admit of the valve moving independently of the valve stem, and a coil spring surrounding the spindle and interposed between the valve and the inner end of the valve stem.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

BELA BERGER.
